Malachi 3:2-4

Orthodox Jewish Bible

² But who may abide the Yom Bo’o (day of His coming)? Who shall stand when He appeareth? For He is like a refiner’s eish, and like fullers’ soap:

³ And He shall sit as a refiner and purifier of kesef; and He shall purify the Bnei Levi, and purge them as zahav and kesef, that they may offer unto Hashem an offering in tzedakah.

⁴ Then shall the offering of Yehudah and Yerushalayim be pleasing unto Hashem, as in the yamei olam (days of old), and as in shanim kadmoniyyot (former years).
